What is the suggested class interval for a frequency distribution if the data ranges from 100 to 220 with 50 observations?

It depends on how tightly clustered the observations are.
The answer would be different if the observations were 100, 102, 104, 107, 110, ... as opposed to 100, 150, 150, 150, 150, ... , 150, 220!

Open ended class within the frequency distribution?
If, in a frequency distribution, the initial class interval is indeterminate at its beginning and/or the final class interval is indeterminate at its end, the distribution is said to possess "open ended" classes.
What kind of frequency distribution graph is appropriate for scores measured on an interval or ratio scale?
histogram
How do you find the population mean for a 95 percent confidence interval?
It depends whether or not the observations are independent and on the distribution of the variable that is being measured or the sample size. You cannot simply assume that the observations are independent and that the distribution is Gaussian (Normal).
The following frequency distribution analyzes the scores on a math test. Find the class midpoint of scores interval 40 and ndash59.?
49.0
What is a modal class interval?
It is the class interval with most number of observations.
What is high modality?
it is a strong word that is used in expositions and arguments if data is in the form of frequency distribution then the modal range is the interval containing the highest frequency of observations
Open ended class within the frequency distribution?

Does a simple frequency distribution provides the frequency of responses for each class interval?
Yes.
How do you work out frequency density?
basically this is an exampleAGE (YEARS) FREQUENCY FREQUENCY DENSITYFD= Frequency DensityAge : 0
What is cumulative percent?
Cumulative percentage is another way of expressing frequency distribution. It calculates the percentage of the cumulative frequency within each interval, much as relative frequency distribution calculates the percentage of frequency.
What is a sentence for class interval?
class interval - one of several convenient intervals into which the values of the variate of a frequency distribution may be grouped.
How do you find out the modal range?
if data is in the form of frequency distribution then the modal range is the interval containing the highest frequency of observations

What is the difference between the normal distribution and Poisson distribution?
The normal distribution is a continuous probability distribution that describes the distribution of real-valued random variables that are distributed around some mean value.The Poisson distribution is a discrete probability distribution that describes the distribution of the number of events that occur within repeated fixed time intervals, where the mean frequency is a known value, and each interval is independent of the prior interval(s)/event(s).
What is a modal class interval?
It is the class interval with most number of observations.
